New Macro Lens

My first shots with my new macro lens. Shot these with manual settings and manual focus. I really haven't gotten anything I really really like yet. I'm finding hard to get a nice sharp focus. Anyway, all C&C is appreciated. Anything at all... lemme have it.

overall they arent bad but due to your aperture of f3.5 the depth of field is tiny. In macro photography especially in areas of 1:1 or greater your going to want an aperture of f8-f16 generally. It'll make focusing a little easier as there is more leeway for mistakes.
#3 is my favorite though. Perfect focus and good detail
